 94 2016-10-03T06:32:48  <wumpus> that wouldn't be a bad idea, actually
 95 2016-10-03T06:33:34  <wumpus> that same path would trigger for people building without HAVE_CONFIG_H, e.g. people trying to build with custom-rolled build systems, such as adding everyting into a MSVC project
 96 2016-10-03T06:33:59  <wumpus> currently one'd get a whole slew of unrealistic defaults (although the windows one would work out)
 97 2016-10-03T06:34:15  <wumpus> would fork out for HAVE_DAEMON I mean. Not for other config.h options
 98 2016-10-03T06:35:53  <gmaxwell> libsecp256k1 does this.

109 2016-10-03T06:52:55  <wumpus> if it keeps running and reporting to logs but not serving requests it seems a deeper issue

111 2016-10-03T07:02:53  <gmaxwell> thats not good.

113 2016-10-03T07:03:57  <gmaxwell> yea, looks like that amazon spy thing is back.. on new IPs.
114 2016-10-03T07:04:15  <luke-jr> they seem to have given up on me still

117 2016-10-03T07:06:08  <gmaxwell> hm. rm my debuglog and kill -HUP appears to have not freed the disk space. (on 0.13.x back a few weeks)

120 2016-10-03T07:07:00  <wumpus> if not the debug log, what is using your disk space?
121 2016-10-03T07:07:34  <gmaxwell> I mean, I had a 20gb debug.log, and 2gb free. Deleted the log. kill -HUP the daemon.. still 2gb free.
122 2016-10-03T07:07:35  <wumpus> oh or is it still holding a reference to the deleted file
123 2016-10-03T07:07:38  <gmaxwell> that.
124 2016-10-03T07:08:06  <wumpus> there's probably some lsof trick to get rid of that
125 2016-10-03T07:09:01  <wumpus> it indicates that there is some fd leak
126 2016-10-03T07:09:10  <gmaxwell> yea, actually I can probably figure out which thread it is.
127 2016-10-03T07:09:47  <wumpus> yes and then you can find the fd in /proc and trunacte it

163 2016-10-03T09:09:27  <btcdrak> wumpus: he is on Telegram reliably.
164 2016-10-03T09:10:08  <wumpus> I really dislike using my phone to chat. But I'll consider it
165 2016-10-03T09:11:34  <wumpus> if only all those zillions of new phone chat programs had an IRC interface, or, even a publically documented API
166 2016-10-03T09:13:11  <btcdrak> wumpus: you can use https://web.telegram.org
167 2016-10-03T09:13:23  <wumpus> its the same silly mess as in the 90's with icq, msn, aol etc all over again, until programs like pidgin came along
168 2016-10-03T09:13:42  <btcdrak> fully agree. it's annoying.
169 2016-10-03T09:14:13  <kinlo> wumpus: bitlbee with libpurple can act as a gateway between telegram and irc.  I have my telegram contacts just in my ircclient like all others

171 2016-10-03T09:29:57  <wumpus> kinlo: there's a libpurple backend for telegram? that's awesome. Hadn't expected so, for some reason, usually those things try very hard to be closed down to third-party applications.
172 2016-10-03T09:30:43  <wumpus> btcdrak: nice, web is preferable to phone at least :)
173 2016-10-03T09:31:18  <sipa> all my contacts are hangouts or irc, both work fine in bitlbee
174 2016-10-03T09:31:32  <kinlo> wumpus: telegram is afaik an "open standard", not a good one, but they are not closed minded like whatsapp
175 2016-10-03T09:31:33  <sipa> eh, irc doesn't even need bitlbee
176 2016-10-03T09:32:03  <wumpus> you're lucky. Some of mine insist on whatsapp, others on signal, others on telegram, others on skype, others on ricochet, ...
177 2016-10-03T09:32:23  <sipa> never heard about ricochet
178 2016-10-03T09:32:41  <kinlo> whatsapp is a bitch, dont assume you'll be able to handle that w/o official client, but telegram, skype, ricochet all have bitlbee options afaik
179 2016-10-03T09:32:49  <sipa> oh, i have signal too, but only with people i can reach in other ways
180 2016-10-03T09:33:39  <wumpus> ricochet is chat over tor hidden services, it's an open source protocol, however I don't think e.g. libpurple integrates it

215 2016-10-03T12:05:50  <wumpus> cfields_: did you know that ssh is set up to pass through LC_* environment variables by default on debian and derivatives? I never knew, just found out with a weird issue. I guess gitian already takes this into account.
216 2016-10-03T12:13:09  <achow101> what are these nodes with 52.x IPs?
217 2016-10-03T12:14:02  <wumpus> achow101: no one knows, guesses range from spy nodes to a (slow) DoS

219 2016-10-03T12:14:39  *** aureianimus has joined #bitcoin-core-dev
220 2016-10-03T12:15:15  <wumpus> it's starting to look more and more like a DoS with the sheer number of connections opened, though opening all those connections could also be a way to deceive the trickle logic
221 2016-10-03T12:15:43  <wumpus> (and hence spy more effectively. I've never seen a spy that was so conspicious though...)
222 2016-10-03T12:17:17  <sipa> seems those stopped connecting to me
223 2016-10-03T12:18:17  <achow101> have you tried iptables to block those connections? I am about to do that.
224 2016-10-03T12:19:20  <luke-jr> I suspect a human is watching us and filtering out our IPs when they figure out who we are
225 2016-10-03T12:19:47  <wumpus> there's a topic on btctalk about it here: https://bitcointalk.org/index.php?topic=1478418.0
226 2016-10-03T12:20:34  <wumpus> achow101: yes you can use iptables based blocking, or bitcoind's ban functionality, getting rid of them is quite easy
227 2016-10-03T12:21:32  *** Chris_Stewart_5 has joined #bitcoin-core-dev
228 2016-10-03T12:23:35  <wumpus> otherwise they leech quite some bandwith. "inv": 383977 * 45 connections, in 3 hours on one of my nodes
229 2016-10-03T12:24:53  <wumpus> if it's a DoS it's a sneaky kind of DoS because they don't have to send you data, they don't send anything besides pong,verack and version, but they can just wait for you to send them tons of invs
230 2016-10-03T12:25:40  <sipa> damn, since last thursday i've uploaded 250 GB worth of blocks
231 2016-10-03T12:26:21  <wumpus> wow
232 2016-10-03T12:27:09  <sipa> .. or my statistics patch is wrong
233 2016-10-03T12:27:42  <wumpus> luke-jr: it's very possible for their operators to listen in here, yes
234 2016-10-03T12:28:11  <sipa> or just notice they're getting banned and stop trying
235 2016-10-03T12:30:16  <achow101> those are all Amazon IPs so we could report them to Amazon and see if they will stop them
236 2016-10-03T12:30:30  <wumpus> yes, we should.
237 2016-10-03T12:30:43  *** jtimon has joined #bitcoin-core-dev
238 2016-10-03T12:30:59  <wumpus> I've been too lazy to report them up to now, but we certainly should, there more people do the better
239 2016-10-03T12:32:02  <wumpus> apparently they all suddenly reconnected about 300-400 seconds ago
240 2016-10-03T12:35:41  <sipa> here as well
241 2016-10-03T12:36:21  <wumpus> they're as conspicious as one can get, either this is some extremely unethical research project, or a troll action explicitly set up to provoke a response

248 2016-10-03T12:40:24  <wumpus> well with two service bits it could in principle support three ranges, maybe that would be another threshold
249 2016-10-03T12:41:03  <sipa> one eight goes to blocks up to depth 300
250 2016-10-03T12:41:26  <sipa> next week or so i'll make some graphs

308 2016-10-03T15:29:10  <BlueMatt> or is that a big change to fix that small bug?

321 2016-10-03T15:47:52  <sipa> BlueMatt: but that change will cause some logic to switch immediately in .13.1 rather than only after segwit activates
322 2016-10-03T15:47:56  <sipa> maybe that's safer
323 2016-10-03T15:48:01  <sipa> i can't check now

328 2016-10-03T15:54:32  <sipa> BlueMatt: i think in general that it's fine to switch things based on segwit being defined rather than active
329 2016-10-03T15:54:50  <sipa> as it will expose problems with relay earlier, and not all at once on the network
330 2016-10-03T15:56:27  <BlueMatt> sipa: ok, I'll open a pr that does just that since it would be weird to have that in a compact block-related pr
331 2016-10-03T15:57:57  <BlueMatt> fwiw, a brief glance indicates this same bug might exist in INV processing
332 2016-10-03T16:07:08  <sipa> BlueMatt: we should have made inv-based announcements obsolete for cb and/or segwit
333 2016-10-03T16:07:34  <BlueMatt> sipa: yea, I was just looking at that code, I really dont like it
334 2016-10-03T16:07:55  <BlueMatt> sipa: i really want to rip out the request there and only respond with getheaders, but too late for 0.13.1

380 2016-10-03T18:24:50  <Chris_Stewart_5> Is there a BIP for the serialization/unserialization for coins.h?
381 2016-10-03T18:26:14  <gmaxwell> no, bips are for interoperability. the internal encoding is purely internal and could change freely from version to version.

383 2016-10-03T18:36:19  <roasbeef> BlueMatt: yeah, although we don't fully utilize the new feature when receiving (only if we're still in checkpoint sync realm do we fetch blocks immedately from headers)
384 2016-10-03T18:40:58  <GitHub86> [bitcoin] TheBlueMatt opened pull request #8872: Remove block-request logic from INV message processing (master...fetchflags2) https://github.com/bitcoin/bitcoin/pull/8872
385 2016-10-03T18:41:04  <BlueMatt> roasbeef: just asking in the context of https://github.com/bitcoin/bitcoin/pull/8872 ie can bitcoin core stop requesting directly on INVs and only request on headers messages
386 2016-10-03T18:41:14  <BlueMatt> sdaftuar: noticed another reason why this is good "Finally, this removes the one place we MarkBlockAsInFlight (ie will forcibly store the block on disk in AcceptBlock) without having seen the header first."

392 2016-10-03T18:45:52  <Chris_Stewart_5> Thanks for the explanation gmaxwell
393 2016-10-03T18:45:58  <gmaxwell> Np.
394 2016-10-03T18:46:39  <gmaxwell> What remaining OpenSSL dependencies do we have in bitcoind?  I am aware of the RNG, though its now far less critical due to the just in time urandom usage for key generation.
395 2016-10-03T18:47:31  <gmaxwell> and tests.
396 2016-10-03T18:48:12  <sipa> i believe that is the only openssl dependency for bitcoind
397 2016-10-03T18:49:25  <roasbeef> BlueMatt: gotcha, yeah that change should be fine from btcd's PoV

405 2016-10-03T19:09:15  <instagibbs> or is that extra-bitcoind(i dont know that stuff)
406 2016-10-03T19:09:22  <sipa> bitcoind does not support the payment protocol
407 2016-10-03T19:09:32  <sipa> it's only in qt
408 2016-10-03T19:09:35  <instagibbs> kk
409 2016-10-03T19:09:44  <gmaxwell> yea my bitcoind qualification was intentional.

485 2016-10-03T22:48:55  <luke-jr> sipa: perhaps, but boring and easy tend to overlap a lot, and tests and review help one learn the codebase well

498 2016-10-03T23:02:17  <luke-jr> that's part of learning the codebase IMO
